I doubt if any court is going to enforce what the landlord is trying to do to you.

But to be on the safe side I suggest you study up on the NJ landlord tenant statute.

Here is a guide to the statutes.

Where statute numbers are provided make sure you read the actual statute and don't rely on just the guide.
